To avoid wasting everybody's time when trying to debug --load
command.load, rename the option to be more explicit about what it does.
Also implement some basic guards in the form of testing that the
filename extension is part of a very short whitelist: .lisp, .cl, .lsp
and .asd.
It might be important to be able to use the exact same pgloader commands
file but adapt its source and target depending on the environment where
the command is to be run (production, development, staging, etc).
Introduce the new sub-clause GETENV 'variable-name' to that effect.
The regression test facility that we have now isn't nearly sophisticated
enough to support this, so the feature isn't yet covered.
Given than redirecting a tty such as *terminal-io* isn't easy enough,
let's provide a way to copy the summary output to a file. Another way to
solve it would have been to output the summary to the main logs, but
that could have made the logs parsing more difficult that necessary.
Let's see how users like it...
With this the user is now able to have a way about where the files are
going to be read and matched against the regular expression. It used not
to be necessary in the archive expansion mode, but is required now that
the feature is exposed in more cases.
That allows using the same SQL files as usual when using pgloader, as it
even supports the \i and \ir psql features (and dollar quoting, etc).
In passing, refactor docs to avoid saying the same things all over the
place, which isn't a very good idea in a man page, at least as far
editing it is involved.
As from now, to install a new version of pgloader when you have an older
one, say because there's that bug that got fixed meanwhile, all you need
to do is run
$ git clone https://github.com/dimitri/pgloader.git /tmp/pgloader
$ pgloader --self-upgrade /tmp/pgloader <options as usual>
Any Common Lisp developper using the product is already doing that many
times a day, it might prove useful for users to be able to hot-patch
themselves too, after all.
Allows packaging systems like Homebrew to install manual pages
automatically for users without introducing a dependency on the manual
page build system.
